Abstract

An electronically-controlled method is provided for manufacturing a ceramic matrix composite structure with a desired shape. The electronically-controlled method comprises picking a first ceramic matrix composite ply that is sandwiched between a first bottom backing film and a first top backing film, and peeling away the first bottom backing film from the first ceramic matrix composite ply. The electronically-controlled method also comprises placing the first ceramic matrix composite ply on a tool surface with the first top backing film facing away from the tool surface, and positioning a vacuum membrane against the first ceramic matrix composite ply that is on the tool surface to provide a vacuum-tight seal against the first ceramic matrix composite ply. The electronically-controlled method further comprises drawing a vacuum to pull the vacuum membrane against the first ceramic matrix composite ply and thereby to form the first ceramic matrix composite ply to shape of the tool surface, and releasing the vacuum. The electronically-controlled method also comprises after the vacuum is released, peeling away the first top backing film from the first ceramic matrix composite ply and thereby to provide the ceramic matrix composite structure with the desired shape.
